Glenn Gordon has collected some examples of his favorite "encountered" art. And some of them aren't even meant as art. Isn't this kind of "noticing" what photographers do? (David Vestal once referred to photographers as "professional noticers.")
A quote: "...the minimalist ideal—divine economy, the feeling of zero—is a state to be striven for...it’s sort of what Zen and yogic practice aspire to...the antidote to bloat."
Featured Comment by Robert Meier: "This column is a great example of Glenn's work, which I've been reading for a long time. He has a quirky, individual, iconoclastic point of view and writing style that are refreshing, inspiring, and just plain wonderful. Thanks for including this here—he deserves the exposure."
Mike adds: I'll say 'ditto' on every point.
